Complete HVAC installation in Dover ranges from $7,000 to $15,000 for a mid-efficiency furnace and AC combination — typically an 80 percent AFUE furnace paired with a 14.3 to 16 SEER2 condenser. High-efficiency systems with variable-speed blowers and two-stage or variable-speed compressors run $12,000 to $22,000 but deliver significantly lower operating costs and qualify for federal tax credits. Heat pump systems fall between $5,000 and $18,000 depending on whether the system is single-stage, variable-speed, or a dual-fuel configuration. Ductwork modifications or new duct runs add $1,000 to $5,000. KIC Refrigeration provides detailed written proposals for Dover homeowners with every cost itemized and no hidden fees.
Yes, substantially. Replacing a 10 SEER air conditioner with a 16 SEER2 unit reduces cooling energy consumption by approximately 38 percent. Upgrading from an 80 AFUE furnace to a 96 AFUE condensing furnace saves 16 cents of every heating dollar — the old furnace sends 20 cents up the flue while the new one captures it. Combined with proper installation practices — correct refrigerant charge verified by superheat and subcooling, proper static pressure and airflow at 400 CFM per ton, sealed duct connections, and a programmable thermostat — a new system typically saves Dover homeowners $600 to $1,800 per year depending on home size, usage patterns, and local energy rates.
Correct HVAC system sizing is determined by a Manual J residential load calculation — the ACCA industry standard — that accounts for your home square footage, ceiling height, insulation R-values, window area and U-factor, air infiltration rate, duct losses, occupancy, and the local NH winter and summer design temperatures. As a rough reference, a well-insulated 2,000-square-foot home in Dover typically needs a 2.5 to 3.5 ton system, while a poorly insulated home of the same size may need 4 tons. KIC Refrigeration never estimates by rule of thumb — we run a proper calculation for your specific Dover home to avoid oversizing, which causes short cycling, high humidity, and premature compressor wear.
A standard furnace and AC replacement in Dover takes 1 to 2 days when existing ductwork, gas piping, and electrical service are adequate and the new equipment fits in the same location. A complete system replacement that includes ductwork modifications, new trunk lines, equipment relocation from basement to attic or vice versa, electrical panel upgrades, or zoning system installation may take 3 to 5 days. Multi-zone mini-split installations with 3 to 5 indoor heads typically take 2 to 3 days. KIC Refrigeration provides a clear timeline in every proposal, coordinates scheduling around your Dover home availability, and keeps you informed on progress every step of the way.
